...high-voltage cables, the insulation consists of paper tapes wound around the copper conductor, and impregnated with some heavy insulating oil: the whole is enclosed in a lead sheath. During the process of manufacture, air is inevitably occluded within the insulation and later while the cable is in operation gases are evolved from the oil. With high operating voltages these gases become ionized, and, striking the paper tapes, in time destroy them, literally by bombardment. In addition the heat generated chars the insulation and disintegrates the oils so that the combined effects have made high voltage cables the most unreliable...

Vacuum. Reputedly the oldest of oil companies in existence, Vacuum was founded in 1866, seven years after the first commercial production of petroleum, by Matthew Ewing, inventor, and Hiram B. Everest, grocer, on the basis of a vacuum distillation process which Mr. Ewing maintained could turn petroleum 100% into kerosene. This was a valuable claim because the lighter distillations, such as are used for gasoline, were in those days dumped into rivers as waste-products. When the process failed, Mr. Ewing dropped out, but Mr. Everest developed Vacuum Harness Oil, sold it in second-hand oyster cans...
